Scope of application

Cache

In computer science, a buffer is a region of a physical memory storage used to temporarily hold data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a mouse) or just before it is sent to an output device (such as speakers). However, a buffer may be used when moving data between processes within a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory location in hardware - or by using a virtual data buffer in software, pointing at a location in the physical memory. In all cases, the data stored in a data buffer, are stored on a physical storage media.
